NTED STATES PATENT OFFICE JOHN F. RAMSDEN AND EDWARD BOWLUS, OFMIDDLETOWN, MARYLAND, ASSIGNORS OF ONE-THIRD THEIR RIGHT TO P. W.SHAFER, OF SAME PLACE.

Specification forming part of Letters Patent No. 174,853, dated March14, 1876; application filed February 12, 1876.

To all whom it may concern:

Be it known that we, JOHN F. RAMSDEN and EDW. BowLUs, of Middlctown, inthe county of Frederick and State of Maryland, have invented a new andvaluable Improvein cut in Oilers and we do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the same, reference being had to the annexed drawings,making a part of this specification, and to the letters and figures ofreference marked thereon.

Figure l of the drawings is arepresentation of a plan view of our oiler,and Fig. 2 is a vertical central sectional view of a modificationthereof. Fig. 3 is a side elevation of the modification, and Fig. 4 is aview of the oiler proper as used.

7 The nature of our invention consists in the construction andarrangement of an oiler or oiling device for sewing-machines, as will behereinafter more fully set forth.

In the annexed drawing, A represents a bottle of sewing-machine oil asusually sold, and provided with a cork or stopper, B- 0 represents ametallic tube having parallel sides, or, in other words, of the samediameter throughout, except at the point a, which is contracted, asshown. At the upper end of the tube 0 is a metallic cup, D, either madeof the same metal as the tube, or made separate and soldered thereto.This cup is closed on top by means of a disk, G, of rubber or othersuitable material, tied or otherwise fastened to the cup, so as to makethe cup and tube perfectly air-tight except at the point a. The tube 0is passed downward into thebottle A, through a hole or perforation inthe cork B, and, when thus inserted, the rubber disk G is compressed,which expels some of the air contained in the tube, and the point of thetube being immersed in the oil, on removing the pressure the oil entersthe tube, when the tube is withdrawn ready for use.

The tube being of the same diameter throughout, or having parallelsides, is cleansed of any oil that may be adhering to the outside bydrawing it out through the stopper B. b is a diaphragm of rubber orother suitable material, held to the lower end of the stopper B, so thatwhen the tube passes through the perforation in said stopper it alsopasses through a'minute perforation in the elastic diaphragm I), thusinsuring the most thorough cleansing of the tube. The elastic diaphragmb may be stretched over the neck of the bottle and fastened thereto, inwhich case the perforated stopper may be dispensed with.

Instead of a metallic tube and cup, with elastic disk thereon, we may,use a glass tube, 0, with a short section, H, of rubber tube placed onits upper end, which will operate in the same manner. V

What we claim as new, and desire to secure by Letters Patent, is- 1. Thetube 0, constructed with parallel sides, and provided with contractedpoint a at one end, and with the cup D and elastic disk G, or theirequivalents, at the other end, substantially as and for the purposesherein set forth.

2. A perforated elastic diaphragm, b, at-

tached to an oil-bottle, A, in combination with an oil-tube havingparallel sides, for the purposes herein set forth.

3. The perforated stopper B and perforated elastic diaphragm b, incombination with an oil-bottle, A, and oil-tube O, for the purposesherein set forth. y

In testimony that we claim the above we have hereunto subscribed ournames in the presence of two witnesses.
